Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1a, PBP1b, PBP2a, PBP2b, PBP2x, PBP3, and PBP4, thereby preventing cross-linking of peptidoglycan chains. This leads to cell lysis and death.
Cefiderocol is a cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), particularly PBP3, and is stable against a broad range of beta-lactamases, including carbapenemases, due to its ability to penetrate the outer membrane via the bacterial iron transport system.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
1 gram intravenously over 3 hours every 8 hours in patients 18 years and older with creatinine clearance ≥ 60 mL/min.

Approximately 1.8 hours (range 1.2-2.2 h) in normal renal function; prolonged in renal impairment (up to 30-40 h in ESRD)
Terminal elimination half-life: 2.5-3.5 hours; prolonged in renal impairment (e.g., up to 5-6 hours in severe renal impairment), requiring dose adjustment
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); minimal biliary (1-2%); fecal (<1%)
Renal: approximately 65-70% of the dose excreted unchanged in urine; biliary/fecal: minimal (<1%)
